KNIFE ,AND SHEAHS SHARPENER.

SPECIFICATION forming part of Letters Patent No. 785,048, dated March 14, 1905.

' Application led July 11, 1904. Serial No. 216,117.

To all whom, it may concern:

Be it known that I, JOHN NEWTON RICHIE, a citizen of the-United States, residing at Allerton, in the county of Wayne and State of Iowa, have invented certain new and useful Improvements in Knife and Shears Sharpeners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in combined knife and shears sharpeners.

The object of the invention is to provide a device by which knives and shears may be quickly and easily sharpened.

A further object is to provide means whereby the knife-sharpening devices may be adjusted and means whereby the shears-sharpening device may be revolved, thereby bringing into position Jfor use a newsharpening edge as the previously-used sharpening edge becomes worn and dulled.

Still another object is to provide a device of this character which will be simple in construction, strong, durable, and inexpensive, and which may be easily carried in the pocket.

With these andl other objects in view the invention consists of certain novel features of construction, combination, and arrangement oi' parts, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure l is a side elevation of the device. Fig. 2 is a view of the opposite side of the same. Fig. 3 is an end view, and Fig. 4 is a transverse sectional view showing the means for adjusting the sharpening-blade.

Referring more particularly to the drawings, 1 denotes a supporting-plate which may be formed of any suitable material and which is preferably oblong in shape and has formed in each end of the same V-shaped notches 2.

On one end of the plate l is arranged sharpening-plates 3, each of which is provided with offset outwardly-bent cutting or sharpening edges 4. In the inner ends of the plates 3 are formed screw-holes through which are adapted to pass attaching-screws 5, which are adapted to be screwed into the threaded apertures in the supporting-plate l, thereby securing .this end of said sharpeningplates. In the Opposite or outer ends of said sharpening-plates 3 are formed elongated apertures or slots 6, through which are adapted to be passed adjusting-screws 7, which are screwed into threaded apertures in said supportingplate, thereby adjustably holding said sharpening-plates in place. The position of the attaching and adjusting screws is such that the cutting and sharpening edges of the plates 3 will be disposed in position to form between the same a V-shaped space which is arranged immediately over the V-shaped notch in the supporting-plate l.

Near the opposite end ot' the supportingplate 1 is revolubly mounted a circular shearssharpening disk 8, the edge of which is adapted to project over the inner end of the V- shaped notch 2 in this end of the supportingplate 1, thereby coacting with said V-shaped notch to form a shears-sharpening device. The disk 8 is secured to the supporting-plate by means of a set-screw 9, which may be loosened to permit said disk to be revolved, so that when the edge of the same which coacts with said V-shaped notch becomes worn or dulled a fresh surface may be brought into position to coact with said notch.

When using the device for sharpening knives, the edge oi' the blade is inserted in the V-shaped space between the sharpening or cutting edges of the plates 3, and while being so engaged with said cutting edges the knifeblade is drawn through said space, thereby causing the cutting edges to remove thin shavings from the knife-blade, thus reducing the thickness of and forming or sharpening the cutting edge on the same. The slotted connection of the upper ends of the sharpeningplates with the supporting-plate permits the former to be adjusted or brought near together to compensate for the wear of the same.

To sharpen shears, one of the blades of the same is inserted in the V-shaped notch in the opposite end of the supporting-plate, so that the cutting edge of the same will be engaged with the edge of the sharpening-disk 8 and by drawing said blade of the shears across said edge of the disk a thin shaving will be removed rom the edge of the shears-blade, thereby sharpening the edge or' the same.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacricing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A sharpening-tool comprising a supporting-plate provided with a V-shaped notch at one end, sharpening-plates securedone at each side of said notch by means of binding-screws at their inner ends and by adjusting-screws at their outer ends, said sharpening-plates being slotted to accommodate the adjusting-screws, and the sharpening edges of said plates being bent outward away from the supporting-plate, substantially as described.

In testimony whereof I Vhave hereunto set my hand in presence of two subscribing witnesses.

JOHN NEWTON RICHIE.
